The James Webb Space Telescope

We now have two webcams in the Building 29 cleanroom at Goddard, one showing the left side and one showing the right. The screenshots below are updated every minute. The cleanroom is generally occupied from 8:00am to 4:30pm Eastern, Monday – Friday. There may not be much activity outside of these hours.

The cleanroom is always changing so you may not see the same thing every time. One piece of hardware you can keep an eye out for is the flight ISIM Structure, a large, black, square, “latticed” box. This structure will hold Webb’s science instruments and will sit behind the 6.5 meter mirror. The test versions of several of our instruments are also sometimes visible in the cleanroom.
